EXTENSION-TABLE.

SPECIFICATION forming part of ILetters Patent No. 760,553, dated May 24, 1904.

Application filed March 26, 1902. Serial No. 100,11L. (No model.)

To all whom it )may concern.-

Be it known that I, Docron FRANKLIN OLI- VER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Extension-' lable, of which the following is a specification.

The invention relates to improvements in extension-tables.

The object of the present invention is to improve the construction of extension-tables of that class which are provided with intermediate folding leaves and to provide a simple and comparatively inexpensive table of that character having a series of folding leaves and adapted to permit one or more of the same to be readily arranged for use and capable of being quickly folded beneath the top of the table when it is not desired to use them.

A further object of the invention is to increase the strength and durability of exten@ sionstables, more especially the slides which connect the slidable end leaves or sections with the frame of the table, and to enable such parts at the same time to be constructed with a minimum amount of material.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a plan view of an extension-table constructed in accordance with this invention and partly broken away to `illustrate the arrangement of the slides and the pivot o r pintle of the folding intermediate,

leaves, the latter being arranged for use.

Fig. 2 is a similar view, the intermediate leaves being folded; Fig. 3 is a side elevation partly broken away. Fig. 4C is a longitudinal sectional view, the parts being arranged as shown in Fig. l. Fig. 5 is a detail sectional View illustrating the construction of the slides and showing the arrangement of .stops `for limiting the outward movement of the end leaves or sections. Fig. 6 is a transverse sectional view of the table. Figs. 7 and 8 are detail views illustrating the construction of the hinge for connecting the sections or members of the folding leaves. Fig. 9 1s a detail sectional view showing another form of slide. Fig. 1() is a similar view illustrating the construction of the stops employed in connection with the construction shown in Fig. 9. Fig. ll is a detail sectional view illustrating the construction of the inner supperting-tongues, which are adapted to lift the hinged ends of the sectionsor members of the intermediate leaves to prevent the same from sagging. Fig. 12 is a detail view showing another form of stop for the slides shown in Fig 5 and 6.

Like numerals of reference designate corresponding parts in all the figures of the drawings. v

1 l designate transverse connecting-bars suitably secured to legs 2, preferably by means of screws 3, having lower threads for engaging the legs and provided with upper threads for the reception of nuts 4, which also assist in securing guides 5 to the frame formed by the legs and the transverse connectingbars. The guides, which may be constructed of wood, as hereinafter explained, preferably consistof metal bars or pieces approximately U-shaped in cross-section and provided with upwardly-extending sides having inwardlyprojecting longitudinal flanges 6. The guides form ways for slides 7 of end leaves or sections 8, and the said slides, which are suitably secured to the end leaves or sections, have their lower portions arranged within the guides and are provided thereat with longitudinal grooves 9, located at the outer faces of the slides. The slides have contiguous inner faces which are smooth, as clearly shown in Fig. G of the accompanying drawings.

The end sections or leaves 8, which are slidably connected with the frame of the table, have their outer movement limited by stops l0, consisting,preferably, of L-shaped plates, asclearlyshown in Fig. 5 of the drawings, and `arranged. to be engaged by depending projections 11 of the slides. The L-shaped -plates are arranged within the guides andare secured to the same by screws l2 0r other Ysuitable fastening devices, which pass through the guides and enter the connecting-bars l.

In Figs. 9 and 10 of the drawing-sis illustrated a modification of the invention in which the slides are arranged in guides or ways con- IOO sisting of wooden bars 13, spaced apart, as shown vin Fig. 9, and suitably secured to the connecting-bar 14. rlhe bars 13 are provided at their inner faces with grooves 15 for the reception of the slides 16, which are correspondingly recessed at their outer faces to form interlocking tongues or flanges and which are suitably secured to the end leaves or sections 17. The movement of the end leaves or sections is limited by stops 18, consisting of blocks mounted between the bars of the guides or ways and arranged to be engaged by suitable projections of the slides.

The extension-table is provided with a series f of intermediate transversely-movable folding leaves adapted to be arranged in the same horizontal plane as the end leaves or sections, as illustrated in Fig. 1 'of the accompanying drawings, and capable 'of being folded and arranged beneath the end leaves or sections, as shown in Fig. 2 of the drawings. These intermediate transversely-movable leaves may be'of any desired number, and the central 'and side leaves (shown in Fig. l) are ea'eh composed of two sections connected together by'V hinges 19. The central sections or members 2() and 21'are arranged between the side `sections or members 22 and 23 when the entire series lof leaves are arranged for use, as illustrated in Fig. lof the drawings. The section'or member 2O of the 'central leaf is rigidly secured by suitable fastening ydevices to aoentral 'squared portion 24 of `a shaft or pintle 25, which is provided with rounded `end portions 26, upon which the sections or members 22 -of the side leaves are mounted. The ends 27 of the shaft or pintle are reduced to form shoulders and vare arranged in bearings of brackets or blocks 28, Ywhich are mounted upon the connectingbars 1, as lclearly shown in Fig. 8. The sections or members 22 yof the side leaves kare provided with bearing-blocks 29, `arranged atopposite sides `of the shaft or pintle 'and :engaging the same and permitting the'said shaft or pintle to be placed close to the 'lower faces of the sections 'or members vwhich are mounted upon it. By this construction the se'cti'ons'or members 20 and 22 are :adapted to be'turned or partially rotated independently of one another to fold the intermediate leaves.

Each hinge 19consists, essentially, 'of 'a plate or bar pivoted `at Iopposite sides of the `center by screws 30 or other suitable fastening devices to the seetions'or membersof the intermediate leaves a'nd provided beyond the pivotal points with lower inwardly extending lugs 31', arranged to engage the lower faces of the `sections or members to limit the swing of the `same to retain them in alinement and capable also of limiting the swing' 'of the sections or members when they are folded, whereby the sections `or members are maintained in parallel relation, as clearly illustrated in Figs. 6 and 8 of the drawings. The hinge is preferably provided with plates 32, which are =se cured to the edges of the sections or members, as shown in Fig. 8; but these parts may be omitted, if desired, and the hinges are gained into the leaves and have their outer faces flush with the adjacent edges or faces of the same. In folding the intermediate leaves the sections or members are swung upward and are brought into a positionl parallel with each other, and they are then partially rotated on the shaft or pintle 25 to arrange the lower section or member upon a supporting-cleat 33, as clearly indicated in Fig. 6 of the drawings. The sections or members 2O and 21 of the central intermediate foldable leaf are provided with cleats 34 and 35, secured to the lower faces of the said sections or members and projecting laterally therefrom to form supporting-tongues for receiving the sections or members of the side leaves when the latter 'are in use, and the 'said supporting-tongues 4are also adapted to extend beneath the end leaves 8 when the side leaves are not in use. lhesections or members of the `side leaves are provided with cleats 35 and 36, extending laterally from their outer side edges and forming supporting-tongues, which 'are adapted to extend beneath the end leaves 8, whereby the intermediate sections will be rigidly supported in a horizontal position. The end leaves are capable of a limited :outward movement from the position illustrated in Fig. 1 `of the drawings to free the supporting-tongues of the side leaves to permit the 'latter to fold. The side leaves vare folded in advance of the central leaf, and in unfolding the intermediate leaves the central leaf is first brought to a horizontal position, and by this `arrangement one or more' leaves may be used, as desired. The intermediate folding leaves are supported at the 'center by tongues 37 and 38, secured to the end leaves 8 and extending inward therefrom toward the 4center of the tableand presenting inclined upper faces, whereby they are'adapted to lift the sections or members of the intermediate leaves to a proper horizontal position and are prevented from catching on the same. The tongues 38 consist of plates, which are secured to one of the Iend leaves at opposite sides of the center of the inner edge thereof to provide la space for the centrally-arranged tongue 37 which is adapted to extend between the tongues 38, whereby the end leaves 'are adapted to be brought together. The tongues 38 are located at opposite sides of the inner ends 4of the yadjacent sections or members yof the intermediate leaf, and the tongue y37 is arranged directly beneath the center of the adjacent hinge 19 when lthe parts are arranged as shown in Fig. 1, and the inner and outer supporting-tongueseffectually prevent the intermediate leaves from sagging. The inner supporting-tongues have inclined outer terminal portions, as yclearly shown in Fig. 11 of the drawings, and are provided with horizontal inner or intermediate portions located IOO IIS

Fig. 6 of the drawings.

at the tops of the inclined portions for supporting the hinged ends of the sections or mem-v bers of the intermediate leaves.

Instead of employing an L-shaped stop l0, as illustrated in Fig. 5 of the drawings, the movement of the end sections or leaves may be limited by a transverse pin or rivet 42, as clearly shown in Fig. 12. The rivet or pin forms a simple and efiicient stop, and it also operates to connect the sides of the guide.

The end leaves 8 are provided with side and end bars 40 and 41, designed in practice to be ornamented and forming aprons or shields to conceal the interior mechanism of the table.

In folding the intermediate leaves the section which is mounted on the pintle-bar is simply rotated, and the other section slides on the adjacent side of the end sections or leaves and is supported by the same until it is drawn downward upon the supporting-bar 33, and the continued movement of the leaf mounted on the pintle lwill carry the sections to the position illustrated in dotted lines in In unfolding the intei-mediate leaves the lower or slidable section is lifted slightly to arrange its outer end upon the adjacent slide of the end sections or leaves, when it will be carried outward by the rotation of the section that is mounted on the pintle.

It will be seen that the extension-table is exceedingly simple and inexpensive in construction, that it is light, strong, and durable, and that the slides and the guides are adapted to move freely on each other and may be constructed with a minimum amount of material. It will also be apparent that the inner and outer supporting-tongues are adapted to hold the intermediate leaves iirmly in a horizontal position and that the inner beveled tongues, besides supporting the intermediate leaves, are adapted to maintain the end leaves or sections in proper horizontal aline ment when the parts are arranged as shown in Fig. 2.

What I claim isl. In a table, the combination with a frame, of end leaves slidably associated therewith, a rod pivoted for rotation in the frame, and a plurality of intermediate leaves pivoted through the medium of the rod for independent movement from an active position between the sliding leaves to an inactive position beneath the same, one of said intermediate leaves being' iixedly engaged with the rod for rotating the latter whereby the leaf in moving will turn the rod to bring the weight of the leaves from one side thereof to the other thus preventing sagging of `the rod.

Q. In a table, the combination with a frame composed of trans-verse bars and longitudinal guides rigidly connecting the transverse bars, of legs arranged in pairs at opposite ends of the frame and fixed thereto, end leaves slidable relative to the frame longitudinally thereof, slide-bars secured to the leaves and engaging the guides, a rod pivoted for rotation in the frame, and a plurality of intermediatel leaves pivoted through the medium of the rod for independent movement from an active position between the sliding' leaves to an inactive position beneath the same, one of said intermediate leaves being lixedly engaged with the rod for rotating the latter whereby the rod will be turned to bring the weight of the leaves from one side thereof to the other thus preventing sagging of the rod.

3. An extension-table provided with a folding intermediate leal. and provided with a hinge connecting the sections of the intermediate leaf and composed of a continuous plate or member pivoted at opposite sides of the adjacent edges of the sections to thelatter and provided upon its lower edge beyond the pivotal point with lower lugs arranged to support the sections either in a horizontal position or limit the opposite swing of the same to maintain the sections in parallel relation when folded, substantially as described.

4. In an extension-table, the combination of an intermediate continuous leaf composed. of sections, plates secu red to the sections, and a leaf pivoted at opposite sides of the center to the `plates and provided at its lower edge with lugs located beyond the pivotal points, and serving to support the leaf-sections in either horizontal relation or in parallel rela` tion when folded, substantially as'described.

In testimony that I claim the foregoing as my own I have hereto aiiixed my signature in the presence of two witnesses.
